(STAT News) – The ethical debate about designer babies will probably last longer than the West Antarctic Ice Sheet, but the scientific brawl about the study’s claims has been mostly resolved. In new papers published Wednesday, two groups of scientists detail why they think the researchers who created the CRISPR’d embryos goofed. But in a reply, Shoukhrat Mitalipov of Oregon Health and Science University and his colleagues reject the criticism, reporting that they re-tested the embryos — and got the same results.
